Trail Ridge Road Climb β€” Grand Lake

Highlight (Segment) β€’ Climb

Mount up for a truly epic road bike climb up the west side of Trail Ridge Road in Rocky Mountain National Park, starting near the Colorado River Trailhead. This is the highest continuous paved road in North America, so your road bike is perfect for the surface, though expect significant elevation and potentially dramatic weather changes. Over approximately 12.3 miles, you'll gain around 3,178 feet at an average gradient near 4.9%, leaving the subalpine forest behind surprisingly quickly to enter the stunning, exposed alpine tundra above the treeline. The views are absolutely immense as you climb, offering vast panoramas of the surrounding mountains, the expansive Kawuneeche Valley below, and a unique high-alpine landscape where you might spot hardy wildlife like elk or marmots amidst the low-lying tundra plants before reaching the 12,183-foot summit.
